A Stud finder may have a few different names, such as stud sensor or stud detector, but it’s basically a handheld tool that can help you to locate the framing studs in a wall. It can be important, particularly if you don’t have drafting plans of your home, because many homeowners need to know where the studs in their walls are, in order to securely install paintings, pictures, mirrors, or even built-in shelving to the walls.
It’s also helpful to know where fasteners or wiring is in the walls, so you can avoid hammering in nails or screws at these locations, which can cause damage.
How Does a Stud Finder Work?
There are generally two different types of stud finders: moving magnetic detectors, and stationary magnetic detectors.
The magnetic stud detector is built with magnets and it locates the metal within the wall by the magnet being pulled toward the metal. The strongest pull will be felt at a metal fastener in the wall, which will generally give the location of the stud, as the drywall is generally bolted down to the wood part of the stud. Hopefully, the building was made with care, and doesn’t have the metal fasteners too close to the edge.
There are two different types of magnetic stud finders: stationary and moving. You must move the stationary detector around the wall, while with the moving magnetic detector the internal magnets actually move toward the fasteners in the wall.
For electronic stud finders, they’re built with sensors that can detect changes in the wall. Some of them can detect metal, while others can detect live AC voltage. For this type, you have the choice of edge finders, centre finders, and instant finders.
Edge finders can find the edges of the stud, while centre finders detect the middle of the stud. Instant stud finders are the most recent invention, and they come with multiple sensors and do not need to be moved around a wall. They can also detect a multiple amount of studs on the wall. These types aren’t as affected by anomalies in the surface of the wall.
Features to Consider When Buying a Stud Finder
When you’re purchasing a stud finder you’ll want to search for specific features to make your task easier. Remember that one stud finder may not be perfect for everyone, so you’ll need to decide what features are more important to you. Here are a few basic features to consider before ordering that stud finder online.
- Digital/electronic or magnetic. The basic stud finders utilize magnets, which don’t require any batteries at all. For the stud finders that do take batteries, generally they offer additional features beyond finding the studs in the walls.
- Hands-free usage. A hand-free stud finder means that it will find the studs in the wall, then stay attached to the wall on its own, so that you can mark the spot with your pencil. Some of the larger stud finders must be held constantly against the wall.
- Built-in level. A built-in level will enable you to draw a line, so you can hang that painting, mirror, or shelf on the wall evenly.
- LED lights. Some have LED lights that light up when it’s found a stud or metal. They can also indicate the width of the stud.
- Sound. Many stud finders will beep to alert you to when it’s found a stud, which is helpful if you can’t keep your eye on the stud finder all the time.
